Some applications require an input voltage higher than the breakdown voltage of the IC supply pin. In boost converters and SEPICs, you can separate the VIN pin of the IC from the input inductor and use a simple zener regulator to generate the supply voltage for the IC...

SEPIC generates 5V at 100 mA
555 timer draws zero off current
In this Design Idea, we’ve taught the classic 555 timer IC to consume zero current in its quiescent mode and wake up quickly in a known state...
Analog Devices Announces High Speed I2C to CAN-Physical Transceiver
Analog Devices has introduced the robust high speed transceiver LT3960 that extends a single-master I2C bus through harsh or noisy environments at up to 400 kbps using the CAN-physical layer...
Polarity protector outperforms Schottky diodes
The polarity-protection circuit is a high-performance alternative to the usual series diode (often Schottky). The circuit incurs a much lower voltage drop than even the best Schottky diode...
Toshiba Introduces High-Current Photorelay Optimised for Industrial Implementation
Toshiba Electronics Europe has just announced a new addition to its expansive optoelectronics portfolio. The TLP241B is a high-current Photorelay, targeted at use in industrial equipment...
Bootstrapping allows single-rail op amp to provide 0V output
Many single-supply-powered applications require amplifier-output swings within 1 mV – or even submillivolts – of ground. Amplifier-output-saturation limitations normally preclude such operation...
TDK offers compact transformers for DC/DC converters
TDK Corporation presents the EPCOS E10 EM series, a new range of insulated SMT transformers that are suitable for various DC/DC converter topologies and gate driver circuits in e-mobility and industrial electronics...
